Provides a function-based API for estimating heat loss per unit length and annual heat loss from a hot pipe, with or without insulation. The iterative solver converges on the surface temperature and interface temperature using heat transfer correlations for forced and free convection and radiation. Air properties are computed from fourth-order polynomial fits to tabulated data.
